IMPROVEMENT m ELEVATORS.

Specification forming part of Letters Patent No. 176,986, dated May 2,1876; application filed April 12, 1876.

To all whom it may concern:

Be it known that I, THOMAS OHAGAN,

of the city, county, and State of New York,

have invented a new and useful Improvement in Portable Elevators, whichimprovement is fully set forth in the. following specification,reference being had to the accompanying drawing, in which Figure 1represents a side elevation of my improvement, partly in section. Fig.2is a cross-section of. the same. Fig. 3 is a front view of the indicatordetached.

Similar letters indicate corresponding parts.

My improvement relates especially to that class of elevators to be usedin buildings in process of construction, for elevating the differentmaterials that may be required in the upper stories; and it consists incombining, with the platform of such elevators, an index which is somade that it can be set by a workman in the upper part of the house, toinclicate to another workman on the ground-floor the kind or kinds ofmaterial required to be elevated-whether brick,mortar, sills andlintels, or other material. It consists, also, in combining with theplatform a hinged rack, for receiving and holding the hodscommonly usedfor carrying mortar and bricks, such rack being so constructed that itcan be retained in a horizontal or other position in which it is bestadapted to receive and hold the hods, and being hinged in such a waythat it has a tendency to swing downward; hence, if the rack is soconstructed that when it is loosened, so as to permit it to swingdownward, it clears the hods, the latter are automatically released,while the rack is brought out of the way.

In the drawing, the letter A designates the frame of my elevator, and AA and A are the floors of a building. In the upper part of the frame Ais mounted a shaft, B, carrying two drums, O C, over which pass ropes orchains a a. To one end of each of these ropes or chains is secured aplatform, I), while to the other end thereof is secured a second platform, I), in such a manner that by imparting a revolving motionv to theshaft B the one platform'is caused to descend, while the other iselevated. The platforms are guided in suitable ways formed in the frameA, and to the shaft B are secured cranks E, for the purpose llyilp ofturning it. With the platform D is combined an index, F, composed of adial-face and a series of indicating-hands, as clearly shown in Fig. 3.The dial-face of the indicator is, in this example, divided into rings,marked, re-

spectively, Brick, Mortar, and Sills and Lintels, but it is obvious thatit can be dilow, what kind or kinds of material are needed.

The platforms are each provided with a vertical wall, and to the wall ofthe platform I) the index F is fastened. The Wall of the platform Dcarries a bod-rack, G, which is connected to such wall by means ofhinge-joints b b. At one end of this rack G is situated a bracket,

.11, which has a hole formed in it, as at c, Fig.

2. When the rack G is swung up a suflicient distance, so that a pinpassed through the hole 0 in the bracketH comes under the rack, thelatter is thereby firmly held in position, while, when this pin isremoved, the rack falls downward by its own weight. The hole a in thebracket H is so made that when the rack F is held up by a pin passedthrough it the rack occupies a horizontal position, so that the hods canreadily be placed therein. The rack is made with a series of recesses,d, in which the staffs of the hods are placed, and when the rack isallowed to swing downward these recesses clear the hods, so that thelatter can be taken away without obstruction, the rack being, at thesame time, brought into a narrow compass, and the platform being adaptedto be used for carrying sills andlintels, and other materials. besidesbricks and mortar.

In practice I intend to combine the indicator F and the hinged rack Gr(either or both) with each of the platforms of the elevator, in casemore than one platform is used.

If desired, an alarm-bell,I, maybe secured to the upper part of theframe A, such bell having a cord, 0, depending therefrom, as seen inFig. 1, and its object being to permit of calling the attention of theworkman in the upper story of a building to the fact that the platformhas been filled and is ready to be elevated. With the frame may also becombined a ladder, J.

It will be seen that by the application of the device or devices aboveenumerated to portable elevators for buildings their operation isgreatly simplified.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the platform of a
